EVAPORATIVE COOLER.

Specification of Letters Patent.

Patented Aug. 8, 1911.

To all whom it may concern:

Be it known that we, WILLIAM D. TYSON and THOMAS O. TYSON, citizens of the United States, residing at Rosebud, Falls county, Texas, have invented certain new and useful Improvements in Evaporative Coolers; and we do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to certain improvements in evaporative coolers and the like; and the objects and nature of the invention will be readily understood by those skilled in the art in the light of the following explanation of the accompanying drawings illustrating what we now consider our preferred embodiment from among other formations within the spirit and scope of our invention.

The invention consists in certain novel features in construction and in combinations and arrangements as more fully and particularly set forth hereinafter.

Referring to the accompanying drawings, Figure 1, is a perspective view of the cooler with the evaporating fabric partially broken away. Fig. 2, is a perspective view showing the cooler knocked down and the parts packed in the bottom or base pan. Fig. 3, is a vertical longitudinal section. Fig. 1, is a vertical cross section. Fig. 5, is a detail perspective.

In the drawings, 1, is the open top enlarged bottom or base pan, at its four corners having exterior vertically disposed loop like sockets 10, rigidly fixed thereto and longitudinally open to removably receive supporting legs 2, fitted longitudinally in said sockets and extending downwardly from the open ends thereof to support the pan in an elevated position. If so desired, these supporting legs 2, can be formed of flat bar metal bent to limit their upward movement in the sockets. This pan can be formed with an overflow pipe 11, at its upper end opening into the interior of the pan at the level at which it is desired to maintain water in the pan and extending to any desired point at the exterior of the pan to carry off the waste or overflow from the pan.

Four similar posts or uprights 3, rise from the four corners of the pan to the desired height to carry the various supporting shelves and top water pan. If so deslred, each post or upright, can be formed of flat bar metal and these four uprights usually converge upwardly and are arranged in pairs. Each upright at its lower end is doubled upwardly to form a V- shaped lower supporting end or leg 30, at 1ts apex resting on the bottom of the pan while the outer extremity of the upright is bent downwardly to extend over the edge of the pan and form a downwardly projecting end 31, extending into the upper open end of one of the exterior sockets 10, into which said end 31, extends longitudinally with suflicient friction to normally hold the uprights to the pan. The V-shaped lower ends of the uprights space the same inwardly a distance from the ends of the pan, while the sockets 10, are so arranged as to space the uprights inwardly from the sides of the pan. The upper ends of the four uprights support the top water pan 4, and this top water pan is smaller in length and breadth than the bottom or base pan and the depth thereof is also preferably less than the depth of the base pan. This top pan is removably mounted on the upper ends of the four uprights. For instance, in the specific example illustrated, we show this top pan provided at its ends with rigid exterior sockets 40, closed at their upper ends and open at their lower ends, to removably receive and fit down on the upper ends of said uprights. This upper pan is provided with a central opening 41, therethrough, surrounded by a vertical guard wall, whereby the top pan is formed with an annular water space. This central opening is closed against passage of foreign material therethrough by a metal screen 454:, which is secured to the top edge of the guard wall. Certain advantages are attained by securing this screen to the top of the guard wall and thereby closing the top end of the opening and avoiding the formation of a pocket or well within the guard wall to catch particles of food and other foreign matter.

Any suitable means can be provided for supplying water to the top pan. Water can be supplied directly to this pan from a faucet connected with a water supply system, or if so desired a separate or removable water supply tank 5, can be provided having detachable supporting legs 50, resting in the top pan, and a faucet or drip cock 51, through which the water can drip from the supply tank into the top pan.

Between the base pan and the top pan, the four uprights support any suitable number of shelves adapted to receive the articles or receptacles containing the material to be kept cool, and a low temperature is maintained between these shelves by evaporation of water or other suitable fluid. The spaces between the shelves and base and top pans is inclosed by any suitable means. For instance, we show a suitable fabric 6, at its upper edges dipping into the water in the top pan, and secured to the top pan by any suitable means such as spurs 60, fixed to the inner surface of the top pan. This fabric depends from the top pan at the exterior of the four uprights and the shelves, and with its lower edge dipping to the bottom pan, and incloses the space between the top and bottom pans. By capillary action this fabric draws the water from the top pan and becomes saturated with moisture and the evaporation thereby created, as well as the evaporation from the excess water delivered into and standing in the bottom pan, maintains the reduced temperature in the space inclosed by the fabric as will be well understood by those skilled in the art.

Any suitable number of shelves can be arranged between the bottom and top pans, although in the specific example illustrated, we show three such shelves. In the particular example illustrated, each shelf 7, consists of a Hat sheet metal plate having upturned end flanges and downward side flanges, and having vertical ventilating openings 70, therethrough at its end portions to promote circulation of air within the cooler and consequently to increase evaporation. Each opening 70, is surrounded by an upturned edge or flange 71, forming a curb or guard wall to prevent dripping or fall of waste or liquid from an upper pan onto a lower pan. These shelves removably rest on suitable horizontal removable cross bars or supports 8. In the example illustrated, we show a pair of supporting cross bars for each shelf and these cross bars are arranged longitudinally of the shelves and are carried by the pairs of uprights. Each cross bar can be formed of fiat bar metal with its extremities 80, turned down approximately at right angles and reinovably fitting in metal sockets 81, rigidly fixed to the uprights so that the cross bars can be detached from the uprights by forcing the same upwardly to remove their depending ends 80, from said sockets. The ends 80, of the cross bars rest against the fiat inner faces of the uprights and the cross bars are set inwardly from the planes of the outer edges of the uprights by projecting the sockets 81, inwardly beyond the inner edges of the uprights. The purpose of this formation is to prevent the side edges of the shelves from projecting outwardly beyond the outer edges of the up rights into contact with the inolosing fabric and thereby prevent the deposit of moisture from the fabric on the shelves. The arrangement is such that the shelves, each consisting of a single plate of sheet metal, rest loosely on the cross bars between the flat faces of the uprights so that the shelves can be easily removed from the cross bars. The entire device can be readily knocked down by removing the shelves, and lifting the cross bars from the sockets 81, lifting the top pan from the upper ends of the uprights, lifting the uprights from the base pan and from the exterior base pan sockets, and removing the legs L, from the base pan sockets 10. The fiat water supply tank can have its supporting legs 50, removed from the tank sockets removably receiving said legs.

All of the parts are usually so proportioned that the uprights, shelves, cross bars and top pan, as well as the supply tank and its legs, can be placed in the base pan for packing and shipment, and material practical advantages of utility are attained by providing such an arrangement.

It is evident that various changes and modifications might be resorted to without departing from the spirit and scope of our invention and hence we do not wish to limit ourselves to the exact disclosure hereof.

What we claim is 1. A knock-down cooler comprising a base pan having vertically arranged exterior open end sockets, depending supporting legs removably fitted in said sockets, uprights rising from the pan and having depending ends rernovably fitted in said sockets, a top pan removably mounted on said uprights, and supports arranged between said pans and removably coupled to said uprights.

2. A knock-down cooler comprising a base pan, uprights rising from and removably engaging said pan, sockets fixed to said uprights, cross bars between said uprights and having depending ends removably fitted in said upright sockets, and a shelf removably resting on said cross bars.

3. A knock-down cooler comprising a base pan having exterior sockets, uprights having their lower ends bent upwardly to form feet resting in said pan with downturned outer ends removably entering said sockets, and shelf supports carried by said uprights.

4:. A knock down cooler comprising abase pan, removable uprights at their lower ends removably engaging said pan and provided with sockets arranged intermediate their upper and lower ends, cross bars between said uprights and at their ends removably engaging said sockets, shelves removably resting on said bars, and a removable top pan having sockets removably receiving the upper ends of said uprights.

5. A knock down cooler comprising a bottom pan having exterior sockets, removable uprights at their lower ends removably fitted in said sockets and at their lower portions depending into said pan, cross bars between and removably coupled to said uprights and set inwardly from the outer edges thereof, shelves removably resting in said bars, and a top pan having exterior sockets removably receiving the upper ends of said uprights.

6. A knock-down cooler comprising a bottom pan, removable uprights rising therefrom, removable cross bars between said uprights, removable shelves formed by plates removably resting on said cross bars and having ventilating openings surrounded by upturned flanges to prevent leakage from one shelf to another, and a top pan re movably resting on the uprights and having a ventilating opening above said openings of the shelves.

In testimony whereof we alfix our signatures, in presence of two witnesses.
